What Causes Bad Cell Phone Signal?
If your cell service goes from decent to unstable, there is always a reason. Let’s go through the most common.
1) Building Materials
Building materials in your house, vehicle, workplace, or run-of-the-mill shopping mall are the main culprits for weaker cell signal in America. Cellular signals have a hard time penetrating metal, tinted low-E glass, concrete, and many other materials.
If you routinely notice service fading in and out while indoors, it’s likely your signal is being blocked by construction materials. Here is a list of building materials that block cell phone signals and by how much.
|Building Material||dB Loss|
|Foliage||-3 to -20|
|Plywood||-4 to -6|
|Solid wood||-5 to -12|
|Plaster||-8 to -16|
|Brick & Stone||-8 to -28|
|Concrete & Cement (6 inches)||-10 to -20|
|Tinted & Low-E Glass||-24 to -40|
|Metal||-32 to -50|
TIP: While not the most convenient solution, try using your phone near an open window or step outside. A better option is a cell phone signal booster. It can help bypass signal-blocking materials and deliver a stronger signal wherever you need it. We will talk more about them shortly.

2) Cell Tower Distance
Cellular signals can only travel so far. It’s unclear as to how far, since some sources state up to 25 miles while others say 45 miles. Actual distance varies depending on frequencies, the transmitter's power, and terrain (buildings, trees, hills, etc.).
The further you are from a cell tower, and the more obstacles in the way, the weaker the signal gets. This leads to "fish tank" voice, constant say-and-repeat moments, and the dreaded one bar service. People living or traveling in rural areas tend to be the main victims.
TIP: Since relocating closer to your carrier's cell tower is impractical for many, cellular signal boosters are the way to go. They use powerful amplifiers and antennas to communicate with far-away cell towers to deliver a stronger signal where you need it. Alternatively, you can switch to the carrier that offers the best coverage in your area.

3) Heavy Cellular Traffic
Cell phones communicate with cell sites to send and receive calls, texts, and data. Cell towers and small cells can only handle so many devices at a time.
In heavily populated areas, all devices are fighting for a spot on the nearest cell tower. As more people connect, the signal becomes weaker for everybody, resulting in dropped calls and buffering videos. This can happen while stuck in traffic, at a festival, or at home during peak hours.
Due to limited capacity, cellular providers have network management policies in place. They throttle your connection during times of congestion after exceeding a certain number of GBs specified on your plan. The more expensive your plan, the more priority you’re given in the network. They also prioritize devices with a stronger connection to the tower.
TIP: To mitigate or end unreliable cell signal due to heavy cellular traffic, consider upgrading your wireless plan. You can also use a signa booster to strengthen the signal transmitted between your cell tower and device. This will allow you to keep your connection strong even during times of congestion.
4) Dead Spots
There are many pockets around the nation that aren’t covered by specific service providers. If you suddenly lose cell service, your home or vehicle may be in a dead zone.
Dead zones are areas without cell signal. They occur whenever there is any kind of obstruction between the user and the cell phone tower or a lack of towers in general.
You can use your carrier's coverage map to find out if you’re in a dead spot.
|AT&T Coverage Map||T-Mobile Coverage Map||Verizon Coverage Map|
Though, coverage maps are purely estimates; they are not 100% accurate. DeadCellZones.com is also a great resource. All data is crowdsourced.
TIP: The best way to get service in an area without signal is using WiFi calling or investing in a Femtocell. Broadband internet is required for both. Occasionally, though, a faint signal is present but too weak for your phone to register. In those cases, a signal booster can help.

Geographic features often cause signal to go bad. Trees, for example, are notorious for blocking cell phone signals. Whether you’re hiking or your house is surrounded by large foliage, the leaf canopy can cause a massive drop in cellular reception.
Mountains, hills, and valleys, too. Just like building materials, cellular signals have a hard time penetrating natural barriers. If you live on one side of a mountain, and the only cell tower in your area is on the other, you’re not likely to get good reception.
TIP: Unless you’re able to cut down the trees or change location, a signal booster is your best bet against natural barriers.
Shockingly, weather can affect cell service. Cell phones transmit and receive electromagnetic waves. Weather phenomena, such as humidity, thunder, lightning, wind, rain, snow, and ice, disrupt the waves, degrading performance.
TIP: Unfortunately, there’s not much you can do about weather, it’s out of anybody’s control. Though, a signal booster can help fine-tune the signal received from your nearest cell tower. Even during bad weather, you'll be able to enjoy reliable talk, text, and data.

7) Blocking Your Antenna
All mobile phones use antennas to transmit cellular signals. Back in the day, phones had extractable exterior antennas. Sure, they were big, heavy, and unwieldy, but their signal was pretty consistent. That’s partly due to their impossible-to-block exterior antennas.
Today’s phones have antennas embedded inside. Anything blocking the antenna, whether it’s your hand, a magnetic plate, or a metal case, can hurt reception. Where exactly the internal antenna is depends on your phone model. A quick Google search can help you identify its location.
A decrease in signal strength due to blocking the antenna may not be noticeable in areas with strong reception. However, it can make a huge difference in near dead zone environments.
TIP: Find the location of your antenna and avoid blocking it with your hand or a magnetic phone mount plate. Try not to use thick or metal cases that can hinder the amount of signal the antenna receives.
8) Low Battery
Cellular phones need energy to maintain a connection with a cell tower. They may struggle sending and receiving a strong signal when the battery is low.
TIP: Don’t put off charging your phone. You may find yourself with a weak signal when you need it most. If you don’t have access to a power source, try to have a charged power bank on hand at all times just in case.

9) Cosmic Events: Solar Flares
Eruptions on the surface of the sun send plumes of gas into the atmosphere and have been known to disrupt mobile phone communications. These so-called solar flares produce shock waves that travel through space. They can disrupt the signals sent to and from a satellite and produce changes in the Earth’s magnetic field. Obviously, this does not bode well for your cellular signal.
TIP: Unfortunately, there is not much that can be done about cosmic events.
FAQs About Cell Signal Suddenly Going Bad
Can a Cell Phone Case Affect Signal?
Yes. Some phone cases can prevent signal from reaching your phone’s internal antenna.
Thin leather, plastic, or rubber cases won’t significantly affect your cell signal. HOWEVER, metal cases, thick battery cases, and the like pose a greater threat to your connection.
Do Magnets Affect Signal?
Electromagnetic fields can cause signal interference, yes.
However, ordinary magnets, such as ones you might find in a bracelet clasp, headphone speaker, or electric motors, will not. There are actually magnets in your cell phones themselves.
Does Weak Signal Drain my Battery?
Definitely. Your phone has to work significantly harder to communicate to and from your cell tower with weaker signal. This results in significantly shorter battery life.
Can an Old Phone Cause Bad Service?
Yes. As cellular technology evolves, so do phones.
Older phones don’t have the technology needed to tap into the best and fastest networks available. While your friends are enjoying crisp calls or ultra-fast data, you may be stuck on an unreliable network. As time goes on, older phones also lose software update capabilities, which help with performance.
Does Smoke Affect Cell Phone Signal?
It can. Smoke can reflect and absorb cellular signals, degrading performance. Higher frequencies are affected more than lower frequencies. By how much depends on the density of the smoke.
